The general quality of Firefox is worse, the tooling is more fiddly, some of it is written in languages which are not as familiar to Microsoft, it is considerably less straightforward to customize; and on top of this, performance is similar at best. Chromium has an architecture which lends itself to deep integration, and the default UI is much closer to Microsoft's own designs.

If Firefox needs "help" from a big boy like Microsoft, it is probably the worse starting point. If WebKit is a good starting point, why is Blink worse? Chromium is more than Blink, and means that the moment Microsoft started with Chromium, they were already close to done. Whereas with WebKit, they would still have to build and test a shell.
> Is MS foolish enough to believe they can have influence on the evolution of the web through github.com/google/chromium pull requests?
I mean, "influencing the web" or otherwise, they accept heaps and heaps of patches that aren't about their core business. The Chromium project is really healthy.

They can fork, but they probably won't need to. Even if they wanted to maintain an entirely separate shell, it is basically trivial to link such a thing in to Chromium.

It doesn't suck.
